Title: Improvements relating to means for actuating the brake shoes of vehicle brake mechanism
IPC: F16D51/56
Filed: 1925-04-03
Abstract: 249,771. Clark, D'A. M., (Bendix Brake Co.). April 3, 1925. Blocks acting on drums.-The cam or equivalent expanding member for the shoes of an internal expanding brake for vehicle wheels is carried by a support which is normally held frictionally in a fixed position, but is shiftable when the brakes are applied, in order to permit the expanding member to centre itself with respect to the shoes. As shown in Figs. 1 and 2, the shaft of the cam 38 is mounted in a support 46 having laterally-extending wings on which sleeves 48 are carried by means of bolts 50. The sleeves pass through slots 54 near the ends of the brake shoes, whilst the bolts 50 pass through elongated slots 51 in the drum cover plate and carry a plate 52 at their inner ends which serves to confine the brake shoes laterally. If the nuts holding the bolts 50 are not too tightly screwed up, the cam 38 is able to centre itself in a brake application by forcing the bearing 46 laterally. As shown in Fig. 1, the brake may comprise a shoe 20 bifurcated at its lower end and pivoted at 32, a shoe 22 pivoted at 34, and a shoe 24 freely jointed to the shoe 22 at 36. The pivots 32, 34 pass through large slots in the shoes 22, 20 respectively. The cam 38 has a short bottom lobe to engage the shoe 20 and a longer upper lobe to engage the shoe 24, thus providing for the greater movement of the latter shoe in a brake application.

Title: Improvements in or relating to liquids comprising silicyl esters
Inventor: HILL DEREK ALFRED WHEELER
Filed: 1947-10-20
Abstract: Up to 5 per cent by weight of an inorganic amide such as sodamide, or of hydrazine, is added to an anhydrous tetra-alkyl-, tetra-aryl-or tetra-aralkoxy-orthosilicate or to such an orthosilicate which has been partially hydrolysed by an amount of water corresponding to less than 1 1/2 mols. of water per mol. of orthosilicate.  The water may be added to the orthosilicate or may be present in the reactants from which it is made.  The resultant composition is stable against gelling but capable of forming by reaction with water a film-forming coating, fire-proofing or bonding medium or a siliceous sol for delustering artificial silk.  In examples, mixtures which gel in a short time are prepared (1) by adding water to sodamide dissolved in ethyl silicate; (2) by adding aqueous alcohol to a solution of sodamide in tetra-cresyl silicate; (3) adding aqueous hydrazine hydrate to a mixture of ethyl silicate and alcohol.  The ethyl silicate employed is prepared by reacting silicon tetrachloride with industrial ethyl alcohol as in Specification 290,717, [Class 2 (iii)], and is thus partially hydrolysed.  Specification 612,622 is referred to.

Abstract: 493,978. Bombing-sights. OESTERREICHISCH UNGARISCHE OPTISCHE ANSTALT C. P. GOERZ GES., and RAABER, H. Oct. 16, 1937, No. 28214. [Class 92 (ii)] An instrument for determining the instantaneous height of fall or time of fall for bombs dropped from aircraft during inclined flight comprises an arm 6, Fig. 1, maintained horizontal and supporting a vertical scale 7 of heights or times, and a second arm 5, in the line of flight of the aircraft, which moves over the scale to determine the desired height or time which is then set into the bomb-release sight. The instrument is shown in its simplest form in Fig. 1. The bar 6 is moved by a handle 6a about a pivot 4 on a bracket 3 which is rotatable in bearings 1 on the aircraft, the axis pin 2 being vertical during horizontal flight. A sight Oh is set by lowering the vertical scale 7 to a reading H corresponding to height for horizontal flight. When the target is sighted along O Oh, the pilot inclines the flight to an angle Y less than the angle alpha, the bar 6 being maintained horizontal and the bar 5 being directed along the line of flight. The reading H<1> then gives the instantaneous height h<1> for setting into the bomb sight. The adjustment 5b allows for the angle between the line of flight and the fore and aft line of the aircraft. Fig. 1a shows a parallel-motion device for adjusting the bar 5 to take account of a head or following wind by adjusting a slide 18 to the wind scale S, the slide carrying a pin moving in a slot in the bar. Fig. 2 shows the instrument applied to a bomb sight as described in Specification 482,860, the back sight 10b being adjustable over a triple scale 9 as described in the prior Specification to give the release angle without knowing the flying speed. If the flying speed is known, a foresight 8a is adjusted on a scale 5a to this speed, the back sight being adjustable on the bar 9 to the mean speed of fall. The bar 9 is adjustable over a scale 6e to an inclination to the vertical to correct for backward drift.

Title: Improvements in and relating to indicating devices
IPC: G01L7/06
Filed: 1949-11-09
Abstract: 664,333. Elastic-diaphragm pressure gauges; indicating-apparatus. BRITISH THOMSONHOUSTON CO., Ltd. Nov. 9, 1949 [Nov. 17, 1948], No. 28735/49. Classes 106 (ii) and 106 (iv). An indicating-device comprises. a bellows having a fixed end, and a free end which is movable in accordance with the pressure exerted on the bellows, wherein co-operating elements of magnetic material are provided, of which one is secured to the free end of the bellows and the other is arranged for reciprocating movement responsive to the magnetic attraction between the two elements and a counter-action exerted by a biassing means, the distance and the mutual attraction of the two elements, and the biassing force being so correlated that the element arranged for reciprocating movement is attracted magnetically by the other element, or is moved in the opposite direction by the biassing means when the free end of the bellows moves in one or the other direction beyond a state of equilibrium, whereby a snap-action is provided for an indicating member in accordance with the position of the free end of the bellows. The invention is shown applied to a high-voltage bushing, wherein a certain pressure must be maintained and comprises bellows 4 secured at one end to a barrier 7 ofnon-magnetic material screwed into the casing 2 of the bushing and supporting a bracket 5 with a permanent magnet 6 fastened thereto. A magnetic cup 9 which may be coloured red slides on a rod 8 fixed to the barrier 7 and is urged away from the magnet 6 by a spring 10 potentially to hide a second cup 11, which may be coloured green. So long as the pressure is sufficiently high the magnet is held by the bellows sufficiently near the barrier 7 to attract the magnetic cup 9 and to hold it against the tension of the spring 10 so as to expose the cup 11 and indicate safety. When the pressure falls dangerously low the bellows carry the magnet 6 away from the barrier 7 and the spring is so adjusted that as the danger limit is reached the spring overcomes the magnetic attraction and snaps the cup 9 away to cover the cup 11 and indicate danger. In order that the indicating surfaces of the cups 9, 11 may be viewed from the outside of the bushing a prismatic lens 12 is provided in the shape of a truncated cone with a part 15 cut away to accommodate the cups, a diaphragm 16 supporting the rod 8 and a gasket 17 and ring 18 holding the lens in the barrier 7 which has slots 19 for receiving a spanner wrench to screw the device in place in the housing 2.

A pre-stressed adjusting device, more particularly for pre-stressing the pass adjusting means of a rolling mill comprises a threaded ring component surrounding a tension anchorage member and bearing against one of the insert members carrying the rolls, a ring- shaped threaded nut co-operating therewith and bearing against the other insert, one of the threaded parts being rotatable and the other non-rotatable and fixed to one of the inserts and the rotatable member being keyed to the tension member so that rotation thereof can also adjust compression nuts threaded on the tension member and bearing on the inserts. Roll carrying insert elements 1 and 2 are connected by a tube 3 which is threaded at its ends to receive compression nuts 4 and 5. The pass-adjusting device fitted between the inserts comprises a threaded ring bolt 7a which forms part of a worm wheel 7 keyed to the tube 3 and driven by a worm 6 and also engages a a nut 8 fixed to the insert 1. If the nuts 8 and 4 have threads of the same pitch then if the nut is locked by a device 4a only the insert 1 will be raised or lowered by the pass adjusting device. At the ends of the tube 3 are covers 11 and 13 and closure members 10 and 12 in which are mounted a plunger 15 supported on a piston 14 and a relief valve 17 respectively. In order to pre-stress the device a plunger 15 is forced into the tube by a piston 14. The increase of fluid pressure elongates the tube and either or both of the nuts 4, 5 may be tightened to take up the play after which the hydraulic pressure may be removed. In another form the drive is applied to a driving wheel (not shown) non- rotatably mounted around the anchorage member 3 and located between the insert 1 and the nut 4 and is transmitted through the member 3 to a ring bolt (not shown) non-rotatably mounted in place of the adjusting nut 7a. In a further embodiment, Fig. 3, incorporating a 3-high roll assembly the drive is applied to a driving wheel 48 which embodies a tubular projection 48a passed through an adjustable outer insert 42 and interconnected by dogs 47 to an adjusting ring 46 which is threaded on relatively fixed nuts 45. The nuts 45 secure a non-rotatably mounted anchorage member 44 which is guided by a key 52 in a central non-adjustable insert 41. A lower insert 43 is adjustable in a similar manner to the insert 42. Specification 855,841 is referred to.
